- GLSL stands for openGL Shading Language, which is how shaders are written in the OpenGL API.
- OpenGL is run by Khronos group.
- OpenGL is a subset of OpenGL that is for embedded systems.
- Other alternatives are:
- Direct3D, part of DirectX, owned by Microsoft,
- Vulkan, next generation OpenGL, also by Khronos group, and,
- Nodes join a cluster (named
elasticsearch
by default).- One node becomes the master node.
- Each index data is divided into shards.
- Internally, an index is a logical namespace that points to one or more shards.
- 5 shards by default.
- Due to how routing works, these shards cannot be increased later; you would need to create a new index.
- Python code, written in
.py
file is first compiled to what is calledbytecode
, which is stored with a.pyc
,.pyo
or.pyd
format.- This bytecode is then executed by the interpreter, on instruction at a time.
- When a module is imported, Python will cache the bytecode of the module as
.pyc
,.pyo
and.pyd
files in the__pycache__
folder. .pyc
is the bytecode of the module..pyo
is the bytecode of the module if Python is ran with optimisation options (-o
and-oo
)
.pyd
is Windows only and is packaged as a DLL.
- The default type is
f64
because on modern CPUs it’s roughly the same speed asf32
but is capable of more precision. - Declaring arrays:
let a: [i32; 5] = [1, 2, 3, 4, 5]
; isize
andusize
types depend on the kind of computer your program is running on: 64 bits if you’re on a 64-bit architecture and 32 bits if you’re on a 32-bit architecture.- Unlike languages such as Ruby and JavaScript, Rust will not automatically try to convert non-Boolean types to a Boolean.
- Rust does not have nulls, but it has
